Suicide Prevention in a Post-Apocalyptic Milieu

There was a guy I was with who kept wanting to kill himself.  I don't remember the specific details.  Maybe it was just his ideation, I don't really remember.

We were in a different kind of world.  I don't really remember the details of that either.  Outdoors.  Vaguely post-apocalyptic.  Lots of homeless camps and we were crossing rivers.

The guy's mother was also there.  She cared about him and did not want him to do it.  The suicide thing.

Then the guy had a gun and kept sticking it in his mouth.  I kept waiting for it to go off.  When he did this, I became far away from him, by circumstance, or design, I don't really remember.

I don't remember if the gun ever went off.  I don't think it did.  That probably would have woken me up.

There were other times later in the dream that we met people who seemed to know the guy.  People from him past.  Weird people.  Giant people.

I imagined that we hiked through this strange environment in a northerly direction.  I thought we should get a tent.  He was strangely connected to this place, and I thought it would be good for him.
However, what I am writing now, and what I actually experienced in my dream, though related, are not the same.
